Circa mid-late 1980s keyboard off a militarized portablePC, made out of extruded aluminum.

I believe this to be a near one-of-a-kind keyboard as I have not been able to find anything similar in any searches. I am the original finder of this keyboard / PortablePC which I found, circa 2007, in a bin marked for disposal.

This keyboard was part of an extruded aluminum sided PortablePC that was clearly designed for military use. The keyboard mounted to the side of the PortablePC, keys facing inward. When unmounted from the side, it revealed a small screen and a few data input types which I cannot remember (floppy is likely). If I remember correctly, the screen even had a small tilt function. The entire enclosure was made of the same extruded aluminum. Compaq had a similarly functioning consumer product: https://collection.sciencemuseumgroup.org.uk/objects/co63293/compaq-portable-personal-computer-with-carry-case-1982-1984

The keyboard is fully functioning as you can see in the video. The key presses are satisfyingly loud with a metallic tin associated with the metal backplate inside. The cord fully resides within a cylindrical opening at the top of the keyboard. Removing the cord and rotating the feet outward closes off the cord storage area. The connector is a 5 pin DIN. The 5 pin DIN to PS/2 dongle and PS/2 to USB dongle is included with purchase.

The keyboard measures approx: WxDxH - 425mm x 245mm x 20mm (16.7" x 9.6" x 0.79")
